Has anyone used the plastic evolution props that are flooding the market? They're not quite as flexible as a Windsor (MAS) but not quite as stiff as an APC. They're also shaped a bit different as an APC. I'm running an 11X5 on a .46FX on an uproar. I was running an 11X6 APC, but it was too fast. I don't see a whole lot of difference between the evo and the MAS ... but then again, it's a 3 1/2 pound plane. Are they supposed to be comparable to APC or MAS or were they meant to be something in between?
